Умоляю ,напишите перевод(:
I ran down the street, past the tall high-rises, past the big fountain with the gold statues in it , past all the traffic , right into Central Park, where it was getting king of dark and cold , but I didn't care. Nobody was going to attack me because I was this five-foot-nine girl running in combat boots,with a big backpack with stickers on it that said SUPPORT GREENPEACE and I BRAKE FOR ANIMALS. Nobody messes with a girl in combat boots , especially when she is a vegetarian . Anyway , I don't know how, but my feet sort of knew where they were going and before I knew it, I was at the zoo. I love the Central Park Zoo. I love the Central Park Zoo. I always have since I was a little kid. It's way better than the Bronx Zoo, because it's really small and cosy and the animals are much friendlier, especially the seals and the polar bears. I love polar bears. At the Central Park Zoo, they have this one polar bear and all he does all day long is the backstroke. I swear! He was on the news once , because this animal psychologist was worried he was under too much stress. It must be awful to have people looking at you all day. But then bought him some toys and after that he was all right. He just kicks back in his enclosure - they don't have cages at the Central Park Zoo, they have enclosures - and watches you watching him. Sometimes he holds a ball while he does it. I love that bear. So after I took out a couple of dollars to get in - that's the other good thing about the zoo : it's cleap - I paid a little call on the polar bear. He appeared to be doing fine. Much better than I was , at the moment. I wondered where that polar bear had come from. I hoped he was from Iceland. We're studying Iceland in World Civ. Iceland has the world's highest literacy rate , because there is nothing to do there but read. They also have these natural hot springs, and everybody goes swimming in them.Once, the opera came to Iceland and every show was sold out and something like 98 per cent of the population attended. Everybody knew all the words to the opera and went around singing it all day. I would like to live in Iceland some day. It sounds like a fun place. Much more fun than Manhattan. After a while it got too crowded at the polar bear enclosure , so then I went into the penguin house. It smells kind of bad in here, but it's fun. There are these windows that look underwater so that you can see the penguins swimming around, having a good penguin time. Little kids put their hands on the glass, and when a penguin swims to them, they start screaming . There's a bench you can sit on too and that's where I'm sitting now, writing this. You get used to the smell after a while. I guess you can get used to anything . ( from " The Princess Diaries " by Meg Cabot )
